Her guilty plea to second-degree murder means she could get up to life in prison but would be eligible for parole.

Lyle Kopenkoskey’s body was found near his pickup truck in Emmet County’s Resort Township, northeast of Traverse City. His family reported him missing after he failed to report to work or return home. An affidavit said police found books about murder, cleaning up crime scenes, forensics and poisons.

According to court records, Kopenkoskey admitted that she took her husband out for a drive and shot him five times with an unregistered .38 revolves. According to court records, Kopenkoskey said she’d told her business partner, a man she had a three-to-four year affair with, about the murder — but claims said no one else played a role in the killing.

In exchange for her plea, Kopenkoskey will face up to 18 years in prison. Also a part of the deal, Kopenkoskey has agreed to testify against any co-defendants.

She remains held in the Emmet County jail. Sentencing is set for Feb. 25.
